Geek favorite Nathan Fillion has signed on for Percy Jackson & The Olympians: The Sea of Monsters, the Thor Freudenthal-directed sequel to Percy Jackson & The Olympians: The Lightning Thief. As Greek god Hermes, father of antagonist Luke (Jake Abel), Fillion joins a strong supporting cast that includes Yvette Nicole Brown (Community), Missi Pyle (The Artist), and Mary Birdsong (The Descendants) as the three Fates.

Logan Lerman, who starred in the first film as Percy, will reprise his role, along with Alexandra Daddario and Brandon T. Jackson. The Sea of Monsters is scheduled to hit theaters March 26, 2013.

After the jump, Halle Berry comes back to The Hive, and Anthony Michael Hall stabs Danny Trejo in the back as Mickey Rourke watches on.
